i.mx6:imx6q: allign MAC address with burned-in ordering
For the i.mx6q, the burned-in MAC address will be the following odering,
fuse: 0x620[7:0] MAC_ADDR[7:0] ---> mac[5]
fuse: 0x620[15:8] MAC_ADDR[15:8] ---> mac[4]
fuse: 0x620[23:16] MAC_ADDR[23:16] ---> mac[3]
fuse: 0x620[31:24] MAC_ADDR[31:24] ---> mac[2]
fuse: 0x630[7:0] MAC_ADDR[39:32] ---> mac[1]
fuse: 0x630[15:8] MAC_ADDR[47:40] ---> mac[0]
This patch also fix the error caculation for the fuse bank[0] address
